2. y= -2
x+ 2y=6

3. x= -2
2x -y =3

4. x= -2
2x +y = -3 ​

Respuesta :

Answer:

4

Step-by-step explanation:

The x value always stays at -2, therefore the equation would be x = -2.

The y intercept is -3, therefore the equation is 2x + y = -3.

Answer:

1

Step-by-step explanation:

y=-2 represents a straight line where y = -2 (constant) this makes only solutions 1 or 2 possible

but if we try to set x to 0 in the second equation of the first two solutions, we see that for x=0 only the first one gives y=-3 as result, and in the graph the red line crosses y axis at point (0,-3)
